|---|---|---|---|---|---|
| Force | Push or pull upon an object resulting from the object's interaction with another object.
🗑
|
||||
| Work | Move or cause to move gradually or with difficulty into another position, typically by means of constant movement or pressure.
🗑
|
||||
| Wave | A periodic disturbance of the particles of a substance that may be propagated without net movement of the particles, such as in the passage of undulating motion, heat, or sound.
🗑
|
||||
| Medium | A substance that makes possible the transfer of energy from one location to another, especially through waves.
🗑
|
||||
| Crest | A crest is a point on the wave where the displacement of the medium is at a maximum.
🗑
|
||||
| Trough | A trough is the opposite of a crest, so the minimum or lowest point in a cycle.
🗑
|
||||
| Longitudinal | Longitudinal waves are also called compressional waves or compression waves, because they produce compression and rarefaction when traveling through a medium.
🗑
|
||||
| Compression | A compression is a region in a longitudinal wave where the particles are closest together.
🗑
|
||||
| Rarefaction | Rarefaction is the reduction of an item's density, the opposite of compression.
🗑
|
||||
| Transverse | A Transverse wave is always characterized by particle motion being perpendicular to wave motion.
🗑
|
||||
| Mechanical | The branch of physics that deals with the motion of material objects.
🗑
|
||||
| Electromagnetic | The waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity.
🗑
|
||||
| Amplitude | The maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.
🗑
|
||||
| Wavelength | A sinusoidal wave is the spatial period of the wave, the distance over which the wave's shape repeats, and the inverse of the spatial frequency.
🗑
|
||||
| Frequency | The number of crests of a wave that move past a given point in a given unit of time.
🗑
|
||||
| Hertz | A unit of frequency, defined as the number of complete cycles of a periodic signal that take place in one second
🗑
|
||||
| Wave speed | Wave speed is the speed at which a wave travels. Wave speed is related to wavelength, frequency, and period by the equation wave speed = frequency x wavelength.
🗑
|
||||
| Power | Power is the rate of doing work, the unit of power is the joule per second (J/s).
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
